position transmitter

4-20mA position transmitter signal conditioning allows industry standard potentiometers to be directly connected to PLC 4-20mA inputs and industrial IO modules. The 4-20mA position transmitter connection is a standard format in industrial measurement and control systems. The 4-20mA signal allows the position measurement to be run much further than the resistive connection of the potentiometer itself. 4-20mA signals can be run directly for thousands of feet, when using the correct cable and power supply. Many PLC inputs either standardly or optionally can be configured for 4-20mA, and it is not unusual to find spare inputs in an installation.

Example 4-20mA thermistor transmitter wiring diagram A Simple 4-20mA Transmitter Operation Description The 4-20mA transmitter can be looked at as a temperature controlled variable load. It is in series with the power supply and current measurement shunt resistance. The effect is similar to the transmitter acting like a potentiometer. One that will vary total load …
